Abstract
This study describes the preparation, biodistribution and absorbed dose prediction of 67Ga and 99mTc labeled bombesin (BBN) in human organs, after injection in mice determined via medical internal radiation dose. We estimated that a 185-MBq injection of 67Ga-BBN into the humans would result in an estimated effective absorbed dose of 2.50 mSv whereas this value for 99mTc-BBN is 1.33 mSv in the whole body. These results suggest that injection of 67Ga-BBN would result 2 times higher absorbed dose compare to 99mTc-BBN.
